Вы можете перехватывать запросы HTTP и задержать их:
сети delay.js
exports.module = function() {
angular.module('networkDelayInterceptor', [])
.config(function simulateNetworkLatency($httpProvider) {
function httpDelay($timeout, $q) {
var delayInMilliseconds = 1000;
var responseOverride = function (reject) {
return function (response) {
//Uncomment the lines below to filter out all the requests not needing delay
//if (response.config.url.indexOf('some-url-to-delay') === -1) {
// return response;
//}
var deferred = $q.defer();
$timeout(
function() {
if (reject) {
deferred.reject(response);
} else {
deferred.resolve(response);
}
},
delayInMilliseconds,
false
);
return deferred.promise;
};
};
return {
response: responseOverride(false),
responseError: responseOverride(true)
};
}
$httpProvider.interceptors.push(httpDelay);
})
};
Использование
beforeAll(function() {
var networkDelay = require('network-delay');
// You can customize the module with a parameter for the url and the delay by adding them as a 3rd and 4th param, and modifying the module to use them
browser.addMockModule('networkDelayInterceptor', networkDelay.module);
});
afterAll(function() {
browser.removeMockModule('networkDelayInterceptor');
});
it('My-slowed-down-test', function() {
});
